Babylonian Planetary Periods & Mundane Astrology


By John Timperman



From the time of the Greek dominance of astrology, we commonly find references to planetary periods. In later times the Hellenistic astrologers and the Arabs used different systems of planetary periods such as “Zodiacal releasing ” and “Firdaria.” but these are systems that have nothing to do with the original model of Mesopotamia.

The authentic planetary periods are based on the heliacal phases of the different planets. The calculations of the astrologers of Babylon were based on the tropical solar year and are repetitions of a specific heliacal cycle in all its details.


A Babylonian Planetary period is the time period after which an exact period of a given heliacal cycle takes place.

Venus, for instance, has a short heliacal period of 8 years minus 2 days. This means that if Venus shows up today in the east in her morning the first phase , then after 8 years less 2 days she will show up again in Morning First, at the exact spot in the sky, same magnitude, same fixed stars background, etc

These heliacal periods of the planets can be of different duration. There are 4 kinds of periods; short, medium, long and giant. Different planets have different sets of them. Venus has only 2 periods; small of 8 years and a giant of 6400 years. Saturn has, according to the Babylonians, only a long period of 59 years and a giant one of 589 years.

GLOBAL HELIACAL PERIODSThis table shows us how we can calculate the periods of a planet and come to know when a planet is ” released ” and when its effect is then maximized.

The procedure is as follows:

the heliacal rise. We see in the above table that the period of Mars is 15-47-79 years which means for this person that 40 days after birth and after every 15-47-79 years the planet is again activated.

This procedure is simply based on the principles put into practice by the astrologer-priests of Mesopotamia:

If someone is born when a certain celestial SIGN was in the sky THEN the significance of this SIGN will come to fulfillment WHEN that same sign is seen AGAIN in the sky.We can apply this system in genethical astrology as I explained in another article, but it is by all means also of interest in Mundane astrology.

When we look at some important events in the US we come across the following data :

July 21 1861- first battle in the American civil war

December 6 1941 Pearl Harbor

September 11 2001 Twin towers terrorist attack

June 12 2016 Orlando massacre

Between the beginning of the Civil War and the Pearl Harbor attack there is exactly 79 years and 6 months which is very close to the long planetary period of Mars. Mars is a planet which is particularly strong in the chart of the US as the planet rises a couple of days after July 4th.

When we look up ( K. Schoch planet- tables, Berlin 1927) when Mars was heliacally rising before the beginning of the Civil War ( July 21st 1861) we come to September 22 1859 which is exactly one year and 10 months before the beginning of the war . This happened with the 9th degree of Virgo and it was also the day of the heliacal rise of Zosma, a martial star in the back of Leo.

When we advance 79 years ( Mars period) and want to know when Mars is rising at about the same degree we see in the tables that this happens at September 25th 1938. When we now move ahead one year and 10 months we arrive in July 1941 : some 4 months before the attack on Pearl Harbor ! It may be interesting to point here that if we go 79 years further we arriving at September 27 2017. So, this means that ,according to this system, in about one year and 10 months mars could be activated again.

When we proceed and also investigate the time between Pearl Harbor ( December 12 1941 ) and September 11 2001 there is exactly 59 year and 9 months. This is around the long cycle of Saturn which we have to examine.

In 1941 Saturn rose heliacally around June 11th at 22° Taurus and some 6 months later there was the attack at Pearl Harbor which incited the US to declare war with Japan and Germany.

It was at the end of January that the Americans stroke back for the first time and attacked the Marshall Islands from the USS enterprise.

The solar chart for 1942, the year that America entered the war at full scale is particularly interesting : Saturn is at 8° Gemini and makes an exact conjunction with the ascendant of the horoscope of the US. We must not forget that at 8° Gemini there is the fixed star Aldebaran whose character is very martial and very important since she is heliacally rising in the chart of the U S.

Solar horoscope US: July 4th, 1942

59 years later – 2001-( heliacal period of Saturn) Saturn is thus rising at the same place and ,in the solar chart we then see Saturn again at 8° Gemini. Two months later America faced the tragedy of 9/11.

Solar horoscope US : July 4th 2001

It is ,for that matter, also interesting to look at the period of time between the tragedy of 9/11 and the shootout in Orlando which happened in June 2016 and which was exactly 15 years.

We come back to the cycle of the short period of Mars. It was approximately  September 6th in 2000 that Mars rose at the 22nd degree of Leo. Exactly one year and a couple of days later there was the terrorist attack on the twin towers.

It was the 23rd of August 2015 that,15 years later Mars was again heliacally rising close to the 10th degree of Leo. About 10 months later, on June 12th 2016 , there was the terrible shootout in Orlando.

For closing, something totally different, but also pertinent to the subject of planetary periods. Consider the Wall street Crash of 1929 also known as Black Tuesday ( October 29) or the Stock Market Crash of 1929 began on October 24, 1929. It was the most devastating stock market crash in the history of the United States.

79 years later in October 2008( the long period of Mars) the investment bank “Lehman Brothers ” filed for bankruptcy and lead the US and the rest of the world into an unseen financial and economic crisis.

When we look to where Mars rose before October 1929 we come to January 30th 1928 where Mars rises together with the 8th degree of Capricorn. This is 1 year and 9 months before “Black Tuesday”

79 years later, on February 14th 2007, Mars rises again, this time at the 21st degree of Capricorn. It is 1 year and 7 months later , in October 2008, that the US faces another huge financial crises.

So we can say that this system of planetary periods and their parameters, once the most important factors to be considered in astrological prognosis, still has merits, although sadly ,it has almost been completely forgotten by contemporary astrologers.
